Universe Sandbox ² is a physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale.

It merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet. Universe Sandbox ² is the long-awaited sequel to the original Universe Sandbox.

Universe Sandbox ² includes the desktop version and a VR mode with support for the HTC Vive & Oculus Rift+Touch. This is a free, automatic update.Simulate GravityN-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.
Collide Planets & StarsEpic, mind blowing collisions of massive planetary bodies.
Model Earth's ClimateWatch sea ice grow and recede with the seasons because of the tilt of the Earth: change the tilt and change the seasons. Or move the Earth farther from the Sun and freeze the entire planet.

Early Access Review Absolutely ingenious Simulation for all Space and science FANS who like a realistic and well-made Solar system for their Home PC and in addition Univserum simulation, the Operation is learned in 15 Minutes and then you can get away from reality n Atordingly also simulating all sorts of stupid things, who doesn't want to make the Earth 4x heavier and bring down the Moon through this increased gravity:) Here is my Video for all undecided: https://youtu.be/8YI35dbww3k

Early Access Review In this Game, the following Skills are desired: Creativity-Mathematical Logic-joy! I start in an empty Universe and can fill it with numerous Objects and watch them react to each other. Black Holes, Galaxies, Stars, Asteroids, Planets and much more will be provided to the Player. Equally physical Properties of the Objects can be determined such as: Temperature, Density, mass, gravity, speed, Etc. As a result, there are hardly any Limits to the Player. I give the Game 7 Out of 10 points For a fluid Gaming Experience should have a medium-strength Intel i5 Processor, at AMD a CPU of the FX 000s Reihesein and the Graphics Chart should have at least 4GB of VRAM.

Early Access Review Fantastic! Really a successful Game! For kanpp 23€ you have everything you need to deny Planets, Suns or whole Galaxies. Viking stunning! If you just want to experiment with two Earth Moondes, for example, you are happy about this Game. But... For example, if I let the Moond bounce to the Earth, only one Explosion occurs, the Earth heats up sicha uf 6000°C and glows. Wouldn't a Part of the Earth break away in real Life? Or if you shoot a Planet at Earth, wouldn't that trigger an incredible Explosion that would break both Planets? So there are a few more Effects missing, but I don't want to howl around, the Game has only been on the go for a few Days and also Early Takes. I recommend it!

Early Access Review Absolute Recommendation for anyone interested in Astronomy, Physics and Entertainment. Here You will learn in a graphically impressive Presentation what happens or could happen in the Universe. Not always everything is completely serious and absolutely exact ... But no other Program offers the same Freedoms to fill the Kit with Toys of astronomical Orders of magnitude and to deal with the Effects of Einstein Relativistics (such as the Gravitational lens in the Environment of black Holes) and Quantum Mechanics ( Neutron Stars and Pulsars) equally playfully approach. And fans of Science Fiction, Fantasy and Nonsense don't miss out either when you send Bowling Balls, archimedic Bodies, Halloween pumpkins or even the T.A.R.D.I.S. on Trips. Verdict: Must Have! Rarely has science been presented with so much Attention to Detail. My Nomination for the "with Love 2018" award. A strong GPU with OpenCL support is recommended. Even a CPU with multiple fast Computing Cores can't hurt.
